The lack of any siping on the tread blocks makes me think they wont do good on ice and compacted snow. I think they would do fine in deep snow. Which I think is what the magazine editors are testing them in. Could be wrong though.
So shop forman called the service rep on my tires and his reply was "must be the way i'm driving it". I can all ready see where this is going.
I would suggest going through forums and printing some of the threads like this one where other people have mentioned abnormal tire wear. Take them in, and even if they don't read them, or claim that they can't prove the posts are real cases of tire wear, at least they're seeing that you've done more research on the subject than they're average customer. Take pictures of your tires and a written explanation of the scenario..... the fact of the matter is, its easier for the dealer to make something up or blame it on you than it is for him to actually go through the process of filing the claim. People are lazy.... if you've got the photos and explanation in hand that he can submit to Ford, he may be more inclined to actually do it.
If this approach doesn't work, I would suggest that you ask to speak to someone in charge at the dealership (like the General Manager) and tell them that you think its a safety issue. Give them the photos and explanation, tell them you have a safety concern with their product, and if they won't make it right then you would like something in writing explaining why. Once you start asking for things about safety in writing, it's like you've brought to their attention the fact that you may be going to a lawyer on this without having to come across as a threatening **** or even using the word "lawyer". Start insisting that all communications with this person be sent back and forth via email so that you have a documented paper trail, but do it politely. They will know what you're up to, but also won't just write you off as some crazy irate customer. If you continually press the matter via email, express the fact that you know in your heart that the abnormal tire wear isn't your fault, and you're not going to give up on the issue and will use every resource available to you to achieve satisfaction.... the GM will probably realize its going to be a lot less time consuming for him to get you some new tires. If he still won't play ball, take all of this documentation and find a way to get it to the owner.
Unfortunately I went through some serious back-and-forth for several months on a similar scenario with an M5 that I used to have. I ended up having to go above the GM/Minority Owner's head and was able to eventually get in touch with the Earnhardt family (yes those Earnhardts) that are the majority owners of the place. They ultimately heard me out and agreed to a fair solution.
The point of this rant is that I found a way to achieve satisfaction from a dealer who at first would not play ball, and never once did I have to raise my voice at anyone or threaten a lawsuit to get what I wanted. I just had to show a hell of a lot of
persistence. That may be more trouble than you're willing to go through for a set of tires, but its all about how much it means to you. Ultimately most people will eventually do right by someone who is approaching them with a problem in an educated and persistent manner that is backed by evidence and a decent attitude. If they don't wanna do right by you at that point, then they're probably still willing to do whatever it takes to get rid of you.
My Old Man always advised me that it's unfortunate that at times you have to play hard ball in business to get what you're fairly owed, but if you do it the right way while getting the message across that you're not just going to roll over and accept "No", then you may not always win, but you will likely have a damned fine-looking batting average.
